Terms in Inbound Balancing
Domain Name
 Refers to an address that is registered at an ISP. An IP address like 198.68.20.78
is not easy to memorize, therefore, domain names intend to represent IP
addresses with meaningful and more easily readable English hostnames, such as
ccu.edu.tw, planet.com.tw.
 We are all familiar with website addresses. For example if we want to browse
yahoo's website we just type in www.yahoo.com into a browser to see the
website. In reality, yahoo's website address is the IP address 66.218.71.84. But
with the help of a DNS server acting as an intermediary, the website address is
mapped to the IP address.
Enable DNS Zone
 Allows users to activate DNS for inbound balancing.
